Due to the presence of the hydrophobic fine particles 2, minute irregularities are formed on the surface of the coating film 5.
- the water repellency of the coating film 5 can be increased by the minute uneven structure on the surface.
- the mass ratio of the hydrophobic fine particles 2 to the binder resin 4 is less than 0.5, a fine uneven structure is not formed on the entire surface of the coating film 5, and the coating film 5 having a desired water repellency cannot be obtained. This is not preferable.
- the flat fine particles 3 in the coating film 5 are characterized in that the table surface and the end surface of the flat fine particles 3 are in contact with each other to form a card house-like aggregated structure. Due to this card house-like aggregation structure, irregularities are formed on the surface of the coating film 5. Due to the surface irregularities, minute irregularities formed by the hydrophobic fine particles 2 are combined, and the ratio of the liquid-gas contact area at the interface between the liquid and the surface in the Cassie formula increases, so that the surface tension is higher than that of water. Super liquid repellency can be expressed even with a small liquid. On the other hand, when the flat fine particles 3 do not form a card house-like aggregated structure, the surface uneven structure as shown in FIG. This surface uneven structure is similar to the surface uneven structure formed when the flat fine particles 3 are not included (see FIG. 5).

Due to the presence of the flat fine particles 3, irregularities are formed on the surface of the coating film 5. Due to the uneven structure on the surface, the water repellency of the coating film 5 can be increased. When the mass ratio of the flat fine particles 3 to the binder resin 4 is less than 0.25, the flat fine particles 3 cannot be dispersed throughout the coating film 5, and the coating film 5 having a desired water repellency is obtained. Since it may not be, it is not preferable.

Abstract
Description
また、特許文献2には、アルコール、アルコキシシラン、パーフルオロアルキルシラン、シリカ微粒子、アルコキシシランの加水分解反応を促進する触媒及び水を含むコーティング組成物をコーティングすることで得られる表面の二乗平均粗さ(RMS)値が100nm以上であるコーティング膜が開示されており、このコーティング膜は、水に対して150度以上の接触角及び油に対して130度以上の接触角を示すことが記載されている。
また、特許文献2では、加水分解反応を利用しているため、コーティング液の調製に時間がかかること、コーティング回数が少ない場合には十分な接触角が得られないため、工程数が多くなるという問題があった。
更に、特許文献1及び2のコーティング膜では、乾燥時にクラックが発生しやすいという問題があった。
本発明は、上記問題点を解決すべくなされたものであり、煩雑な作業を必要とせずに、高い撥水性及び撥油性を付与でき且つクラックの少ないコーティング膜を形成することのできるコーティング組成物を提供することを目的とする。
図1は、本発明の実施の形態1に係るコーティング膜を備えたコーティング物品の模式断面図である。図2は、本発明の実施の形態1に係るコーティング膜を備えたコーティング物品の模式上面図である。図3は、本発明の実施の形態1に係るコーティング膜を備えたコーティング物品の模式斜視図である。これらの図では、基材1の上面に、疎水性微粒子2、扁平状微粒子3及びバインダー樹脂4からなるコーティング膜5が設けられている。
また、扁平状微粒子3の凝集状態の平均粒径が、好ましくは125nm以上200μm以下、より好ましくは10μm以上100μm以下である。扁平状微粒子3の凝集状態の平均粒径が125nm未満であると、疎水性微粒子2によって形成される微細凹凸構造との差が小さくなるために凹凸構造の組み合わせによる撥水性の向上効果が得られない場合があるので好ましくない。また、扁平状微粒子3の凝集状態の平均粒径が200μmを超えると、バインダー樹脂4との密着性が低下し、外部からの刺激によって、コーティング膜5の表面形状が変化してしまい、撥水性が損なわれる場合があるので好ましくない。
超撥水性の評価のために、以下のようにして初期水滴接触角の測定を行った。ここでの「超撥水性」とは、水に対する接触角が150度以上を示す性質のことである。
協和界面科学製のDM301型接触角計を用い、大気中(約25℃)で2μLの水滴をコーティング膜に滴下して、水滴の静的接触角を測定した。超撥水性の評価は、下記評価基準に基づいて評価を行った。
○:超撥水性の基準となる水に対する接触角が150度以上を示すもの
×:超撥水性の基準となる水に対する接触角が150度未満を示すもの
超撥油性の評価のために、以下のようにして初期水滴接触角の測定を行った。ここでの、「超撥油性」とは、水よりも表面張力の小さな液滴に対する接触角が150度以上を示す性質のことである。
協和界面科学製のDM301型接触角計を用い、大気中(約25℃)で2μLのぬれ試薬をコーティング膜に滴下して、水滴の静的接触角を測定した。超撥油性の評価は、下記評価基準に基づいて評価を行った。
○:表面張力が48mN/m以上の液体に対する接触角が150度以上を示すもの
×:48mN/m未満の液体に対する接触角が150度未満を示すもの
